Former Manchester United attacker Antonio Valencia has lavished praise on Lionel Messi, calling him 'unique' and 'one of the best in history'. The Ecuadorian international has locked horns with the former Barcelona ace a few times for both club and country.While he rarely came out on top in their duels, Valencia has nothing but admiration for Messi, who he feels is among the greatest players ever. Speaking to Argentine sports outlet Ole, he said:"Messi is unique; he is touched by God, and we must recognise it. When a player stands out, I like to recognise him, and for me, Messi is one of the best in history. At the time of the Cristiano-Messi rivalry, the bad thing about Cristiano was that Messi was also there."For his incredible achievements with club and country, the Argentine has been widely hailed as the greatest of all time. During his 17 years at Barcelona, he scored 672 goals and lifted 34 titles. He also ended his international trophy drought last year, winning the Copa America with Argentina.GOAL@goalThis season, Lionel Messi means business 377302288This season, Lionel Messi means business 😈 https://t.co/QoEmLl5R5MMessi has now clicked into gear at PSG following a difficult first season, where he scored just 11 times across competitions.
